Allergen Hide and Seek: Learn How to Locate and Kill Household Allergens


Dust and Dander

It's a common misconception that pet hair causes allergies. In fact, it's the proteins in pet dander -- sloughed off dead skin -- that can cause reactions in people. Dander can collect in dust and on many surfaces of the home, like carpeting and sofas, so thorough dusting and vacuuming is recommended on a regular basis. And, if possible, remove carpeting from your home and keep pets out of sleeping areas. If you decide to keep your carpeting, shampoo it frequently. However, you'll want to use a quick-drying machine to keep mold from building up in your carpet. An air purifier with a high-efficiency particulate air (HEPA) filter is another option for keeping dander at bay.

Many of the strategies used for reducing pet dander, such as dusting, vacuuming, using air filters and removing carpeting, can also be used for dust removal. When dusting, use a microfiber or damp cloth; when vacuuming, use a machine with a HEPA filter. In addition, you might consider having your mattresses and pillows encased in allergen-proof covers. Your allergist may be able to recommend products for these purposes. Other dust-removal steps include eliminating clutter, buying washable curtains or blinds, and washing all of the bedding in your home in hot (130 degrees Fahrenheit/ 54 degrees Celsius) every one to two weeks.
